Hi Bob,

Please do not open another thread about segmentation faults. You should try to keep adding to the same thread so that we can keep the answers in the forefont. I believe this is the third or fourth time you have creted a thread to discuss this. The answer is always the same but at least this time you have posted the output and code example.

Reading and/or reporting half an error is of no use to you or anyone else. If we look at you output the error is this:-

wiring_digital.c:163: internal compiler error  Segmentation fault

When I take your error and make a search of google it gives this top result.

https://arduino.stackexchange.com/questions/58495/strange-compiler-error-segment...

When I read the answer in the above link that has a vote it explains clearly the issue and one option to solve. It also gives a link that allows you to understand how to solve properly.

https://github.com/arduino/ArduinoCore-avr/issues/39

When I read the github link it explains how the use of F() strings can cause this and explains an alternative way to work.

When I read your .ino code in your demo error example I see you have made extensive use of F() strings.

Hopefully you can find a solution in all of this one way or another.
